How can 802.11ax increase the range by using 2 MHz channels?
Are these WiFi transmission power limits always for a channel of 20 MHz? So I can increase the transmit power for a narrow 2 MHz channel 10 times?
By lowering the data rate.

Thanks. Some additional remarks:
Noise is distributed equally over the frequency spectrum. If you limit the bandwidth, you reduce the overall noise power.
